Abstract: Organopolysiloxanes (I) contg. units of formula (II) are claimed. In (II), R = -(CH2)-2 -CHMe-; X = Cl, Br, CH2Cl, PPh2, CH2PPh2. (II) are linked through -O- with other units (II) and/or MO4/2, R1MO3/2, (R1)2MO2/2, AlO3/2, or R1A102/2 (in which R1 = Me or Et, and M = Si, Ti, or Zr) and/or units (II) with X = H. The ratio of Si atoms in all units (II) to atoms M or Al is from 1:0 to 1:15. (I) are prepd. from organopolysiloxanes contg. units (II) (with X = H), linked as above, by substn. of a ring-H atom using a reagent (III) in a solvent at -78 to +200 deg.C for a few mins. to several days. After sepn., or distn. of solvent, the prod. is washed, dried at 200 deg.C and, opt., annealed for 1 hr. 5 days at 100-400 deg.C, then milled and/or classified. Specifically, (III) is Cl2, Br2, MeOCH2Cl, EtOCH2Cl, formaldehyde or its Me-or Et- acetal of paraformaldehyde with HCl, and LiPPh2, or KPPh2.

Abstract: In order to produce matee precious metal decorations on carriers of ceramics and porcelain, before applying bright precious metal preparations, the carrier is first provided with a base layer composed of: (a) 50 to 80% by weight of a mixture of (aa) 50 to 80% by weight of a lead-free borosilicate glazed frit with (bb) 20 to 70% by weight of titanium dioxide powder and (b) 20 to 50% by weight of a mixture of (aa) 40 to 60% by weight of a modified alkyd resin having an oil content of 20 to 40% by weight and a solid content of 40 to 60% by weight and (bb) 40 to 60% by weight of an aromatic hydrocarbon.

Abstract: Encapsulation pigments comprising chromophoric particles embedded in glaze-stable casings are prepared by means of calcination from the appropriate initial products. High yields and strong color intensities are obtained if the chromophoric substance or its initial compounds are bound in and/or to a zeolite and are calcined in this form with the remaining constituents.

Abstract: Pressed titanium dioxide is produced by intensively mixing pyrogenically prepared titanium dioxide in the presence of deionised water with a humectant and/or a base and/or, if appropriate, a binder and/or, if appropriate, a forming aid and/or, if appropriate, a pore former, extruding the resulting mass at pressures of between 5 and 100 bar to give mouldings, drying the mouldings at temperatures between 50 and 120 DEG C and then calcining them for 1 to 5 hours in ambient air at temperatures from 400 to 700 DEG C.

Abstract: Element, preferably in panel form, for use as thermal insulation, comprising …… a) a finely dispersed, pulverulant or fibrous substance, … b) a microporous covering and … c) a gas-tight and water-proof metal-free covering. …… The element is produced by drying the pulverulant or fibrous substance, if appropriate, introducing it into a microporous covering, if appropriate, compressing it, if appropriate, and then drying it, if appropriate. After that, the pulverulant substance with the microporous covering is introduced into a gas-tight and water-proof, metal-free covering. If appropriate, this gas-tight and water-proof covering is evacuated and sealed. … …
